A case of Behçet's disease, in which superior vena cava syndrome was the presenting feature is reported. Magnetic resonance imaging and echocardiography revealed a mass lesion in the right atrium. This patient developed bilateral pulmonary artery aneurysms postoperatively and represents one of the bizarre manifestations of Behçet's disease.
In this report, 14 patients with Behçet's disease with a total of 16 aneurysms are presented. The most common site of aneurysm formation was the femoral artery. Patients with Behçet's disease and aneurysm formation carry the highest morbidity and mortality rates among all those with the disease. The results of reconstructive surgery in the treatment of aneurysms are discouraging, with many anastomotic aneurysms and grafts occluding. In this study, it was possible to ligate major arteries such as the common iliac, superficial femoral and popliteal without limb loss. It is suggested that ligature either at initial surgery or reoperation should be performed to avoid complications of reconstructive surgery. Adjuvant immunotherapy is required to control relapses responsible for new aneurysm formation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
